VK-162 GPS support for windows and for linux system, not for android and IOS system | The USB GPS is a great, easy, and an awesome solution for travelers.It works anywhere around the world. After you download the maps for the country traveling, it will pin point exactly where you are without having to pay any service. | For amateur radio operators who need accurate timing for digital communications, this is a unit that will help synchronize the timing for those modes. | This device is extremely accurate. It usually takes a couple of seconds to acquire the initial fix, followed up shortly by acquiring additional satellites for a more precise fix.

🌟The benchtop power board kit was created to provide quick access to the typical voltages needed when developing physical computing projects (embedded systems). | 🌟With power light and power switch. | 🌟Provide quick access to the typical voltages needed including 3.3V, 5V, 12V and -12V | 🌟Each output channel has replaceable 5A fuse and corresponding ground connection with binding post easy to connect | 🌟On-board standard 24pin ATX port, power indicator and power switch easy to control ideal to DIY low voltage power supply for developing physical computing projects (embedded systems)

AM312 Human Sensing Module: Based on passive body infrared technology digital intelligent automatic control products, high sensitivity, reliability, widely used in various types of automatic induction electrical equipment. | Low power consumption, small size, easy to install. | Internal use of digital signal processing, pit interference strong. | Repeatable trigger mode: that is, after the induction output is high, in the delay period, if the body in its induction range of activities, the output will remain high until the delay after the person to become Low level. (Ie, the sensing module automatically detects a delay period after each activity of the human body, and takes the last active time as the starting point for the delay time). | Working voltage: DC 2.7-12V;Static power consumption: <0.1mA;Sensing range: ≤100 degree cone angle, 3-5 m; (required depending on the lens) Working temperature: -20 to + 60 ℃
